RES ILIEN'l TIRE,

To all wiiom it may mm." I

Be it known that I, MORTON HARLOE, a

citizen of the United States, residing. at VVinchester, in the county of Frederick and'fitate of Vir inia, have invented certain new and useful mprovements in Resilient'Tires, of

which the followind is a full, clear, and'exact description, reierencebeing had to theaccompanying drawings, forming part thereof. l I, Z

The present invention relates to improvements in resilient tires for automobiles, trucks, and other vehicles andjis designed to provide adurablegstrong and comparatively inexpensive tire of this type for 'receivingand absorbing the strains from a loadedvehicle,-and for absorbing shocks and jerks in traveling due to irregularities in the road bed and from other causes.

The invention consists in" certainnovel combinations and arrangements with the flexible tire casing of i'nterio1 ly arranged cushioning means and compressible 'means for absorbing movement ofthe' tire casing due to loads thereon, and "in the associatio'n of-parts as will' be'hereinafter'set forth and In the accompanying drawings 1; have illustrated one complete example of the physical embodiment of'my invention constructed according to the best model have so far devised for the practical'application of the principles of o my invention, and based upon extensive and careful study: and ex- 7, perimentation, andz'actual use 7 of the physically embodied invention I have found in actual practice: of the invention certain changes and-adaptations bemade in the tire, but these changes will within the scope of, my-olaims-and do not depart; from the spirit of my invention. 1 p

'or band f proper width is forced in place between the band 3'and the rim sections 4 and 5 to underlap the ed es of the sectional 'joint, for the-purpose'of rictionally holding the sectional rim and band 3.

Thelongbolts 7 spaced around and passing through the wood felly are also passed through the dogs 8 spaced as usual around the tire to clinch or clamp the sectional rim between the dogs and the flanged felly band 3 and by; this means the rim 'is rigidly and securely held in place on the felly.

The-rim sections are each formed with outer, comparatively wide and lnwardly extend1ng,1transverse annular flangesas 9 and '10, leaving'an open space between them communicating with the interior of the hollow riliyand these flanges are fashioned with circumferentially extending, preferably curved ,abutmentffianges ;11 and. 12, which project outwardlyfrom the rim sections as shown.

; The tire casing may be "of standard or acceptable form and ,is fashioned with its gouter; or tread portion 13 vof well known stock material, and an inner portion 14 of composition; fabric material while its side walls 15 and lfiterminate in broad beads 17 and 18 having flat inner surfaces. to seat upon, thetransversefianges 9 and 10 of the rim s ections,;with theirinner edges against thepirrjumfer'ential flanges 11 and 12 ofthe For-,l olding. tlie tire walls inplacc against lateral movement or spreading, lemploy the side retaining rings 19 and 20, and theretainingrings are held, in positionby the llt-ilizatio, v I qvhich a suitable number are employed for t heipurpose, and pivoted onthe rim sections .by rivetsvor bolts 22.- l:hese clamp members of spaced lugs or vclamps 21, of

and may with equal facility be released in similar manner.

The interior of the tire, 'lSFfOLI-IQBdcWZ hfiH annular cushion member 26, of live rubber, forming part of the tire casing, an'dsfashioned with lateral walls 27 28 adhering to the ,inner face of: the tire casing, a-eentral-aveb 29, and a flat base 30 which projects laterally beyond an annular pier" 31, substantially rectangular lIl-CIOSS sectiomand composed ;of laminated ifabric or composition material that;possessesjflexibility. A pier ringj32 of resilient metal form's the base ring for-the pier, and'thisjbase ring surroundsjthe wide I master sp i g ng'i3 w ic is: inclos id i the hollow rim 7 and retained the-rein by the transverse flanges of the rim.

It Will be noted thatthe construction of the tire is simplepand that itj isdesignedffor strength and,, 1i1rabilitv. while yet pOSSQ ing sutficient ifiexibility and resiliency 'for performing its required'functions, and because of its simplicity of construction and minimum number of-parts, the cost of production sections 4; and are exact duplicates, it will be apparent that theyma-y be p o uc w t f i ityi quent t sffro 8 0 ,7

the same mold, and used at either side of the Wheel, and the same advantage is gained' by utilizing duplicate 'retaining rings 19 and I 20. The laminated fabric, or composition m ter l ncludingt eiabr Q may; b Woun upon the resilient base ring to form the pier and provide ,a substantial foundation .Qfor

"the cushion 26,'whichlatter is made up of g d-q y springy r i n ub er, and as the cushionis protected by the outer casing; from wear, its durability. is, enhanced pleted fiexiblepier isplaced in thetire cascushion, is joined to the interior surfaces .of the casingby heat or acid as usual, thus pro viding a resilient, but substantial inner member ofthe tire, supported 0n.'the master spring 33. i v

' It will be noted that the beads '17 and18 o'fthe side walls of the casing; have a substantial and ,wide' solid support on the transverse flanges of the rim sections, in order that the {load of compression on the flexible tire case maybe received .before the movement of compression' is transmitted to thefrubber cushion; The flexibility ,of

the tire casingpermits an upward movement of the tread portion when bearing a sufii-' "ci'ent load, and th s movement lif .great en u h is transmitted through-the rubber cushi lth b i p r, w c of es e i e cy, a fl x b i y t anat .c e

comparatively light loads cause a movement of the tire casing that maybe absorbed by "the cushion member '26 before reaching the fabric, portion ian d spring 33.

But under heavier loads, the greater compresslon move- -ment 0f the tire casing is transmitted through the rubber casing, the flexible fabric pier, the pier ring and finally the master spring or band 33, Where themovement is absorbed. The compression of the cushion member 26 it will be apparent is gradual,

and excessive movementiof the casing is absorbed before the spr1ng83 can reach the inner transverse ,walls of the hollow rim sections, by= the edges of the base 30 of'the rubber -cushion contacting withfand engagingthe outer facesot the inwardly project- .ing,beads 17 and 18 of, the walls of the casing, and the resistance: to the'movement of the deformed or compressed tire casing increases as the compression of parts in-r crefises.
